Leners Patent No. 93,526, ,dans August 1o, 1869-.

The' Schedule referred to in these Letters Patent and making part of thelame.

To all whom it may concern v Be it known that I, J EREMIAH FISHER, ofthe cit of Reading, inthe county of Berks, and State of' Penn'fsylvania,lbave invented certain Improvements in Treat# ing Clay andDrying Bricks; and I do hereby declare that'the following is a full,clear, and exact description ofthe same, reference being had to theaccompanying sheets of drawing, and to the letters of refer` ence markedthereon.

My invention consists in the mechanism used in the" preparation andtransportation ofthe clay,and in drying the raw bricks, but not in themoulding of the same, substantially as is hereinafter shown anddescribed.

On reference to the accompanying sheets of drawings, making part of'thisspecication- Figure 1, sheet l, is a view in perspective, showing myimprovements. v

Figure 1, sheet 2, is a side view, the hoist for raising the hot-air capnot being s'hown'; and

Figures 2 and 3 are side views of the truck used for taking the clayfrom the hopper.

Figure l, sheet 3, isI an end view, and

Figure 2, a plan view of the turn-table. Similar lettersrcfer to similarparts in the several views.

A and B are uppcrand lower floors. The first has the clay-pit O, forreceiving raw unground clay, and to that end is slightly lower than thedoor, to prevent it from spreading, and also forthe more readily con-,veying-to the hopper' D, the upper end of which is on a level` with theupper floor, the lower end being, situated a short distance beneath it,forming, as it were, a communication or passage between the floors. Thehopper .is similar .in construction to those usedv for grinding'clay.

. As the claypasses frprn the hopper, it is caught by the clay-truck L,which, when loaded, is moved on to the door of the elevating-platform E,which 'is raised by the hoist of windlass F, of any suitable construetion, and fixed to any suitable framing above the upper iloor A,immediately over the'centre of the platform, suitable guides, c aI a@,being used to keep the platform from shifting while elevating,

When the oor of the elevator attains the level of the floor A',the truckis turned in the proper direction by means of the turn-table M, on whichit stands, and

passed to the brick-maker.

After the bricks are moulded, they are piled under X the cap G, it'being raised to a suitable heightA by the travelling-windlass or hoistH.

'Gare must be taken to stack the bricks in such manner that a current ofhot air can be readily forced between them, after which the cap islowered.

The fand, which connects with `the exhaust-end of the furnace, used forgenerating steam for driving the machinery, is set in motion by means ofabelted pulley, driven from any adjacent shafting.

The hot air is drawn from the furnace, and forced into the hot-air capG, and. passes in between the bricks, whereby they are thoroughly driedin an incredibly short time, after which it is drawn out by the oppositefan J. It will be seen,sheet 1, in red lines, and sheet 3, fig. 1elevation, that the windlass His movable,'being carried on wheels, whichare carried and travel on the tracks or railway c c, situatedimmediately over. the hot-air cap G, by which means the cap can beelevated and moved While the greenbricks are being stacked previous todrying.

'.lhe truck L forms the table on which the bricks are moulded bythebrick-maker, and to that end the top is made in two parts, which arehinged together at (l.

rlhe part e is capable of being elevated, to throw the clay toward thebrickemaker, at his option, as follows:

g, iig. 2, sheet 2, (showing the side of the truck removed to exhibit.its internal mechanism,) is a toothed sector xed to the under side ofthe vibrating part e, of the top of the truck, depending verticallydownward. h is a shaft passing transversely through one end of thetruck; it carries the pinion k, gearing into the sector g.

It will be readily seen, as the pinion is turned by means of the handleor lever l, fig: 3, it causes the sector g to move .through the arcof avertical circle, whereby the part e is made to take the inclinedposition shown at m, red lines, fig. 2.

After the part e is inclined, as shown, it retains that position throughthe medium of the toothed sector fn, depending from the part c on theoutside of thetruck. When the part e assumes any given. angle, a catch,o, takes into the teeth of the sector 'and supports it.

I do not claim the devices herein shown, either severally or incombination, knowing them to be old; but

What I claim as my invention, and desire to secure by Letters Patent,isv i The arrangement herein described of the two-storied structure, asshown, provided with the clay-pit C, pugmilLD, truck L, elevator E, withits turn-table M and hoist F, hot-air cap Gr, with its fans I- J, andtravellingwindlass I L'up'on its tracks c c,'all constructed andoperated substantially as and for the purposes herein set forth. Intestimony whereof, I hereunto sign my name to this specification, inpresence of two subscribing witnesses. Witnesses: J EREMIAH FISHER.
